Answer:
9/2 +3/2x
Step-by-step explanation:
3/4 (6+2x)
Distribute
3/4*6 + 3/4*2x
18/4 +6/4x
9/2 +3/2x
Answer:
(2,-3)
x=2 y=-3
Step-by-step explanation:
2x+y=1 y=1-2x
3x+2y=0
3x+2(1-2x)=0
3x+2-4x=0
-x+2=0
-x=-2
x=2
2x+y=1
2(2)+y=1
4+y=1
y=-3
(3/x)+(4/(x^2))
give common denominator:
(3x/(x^2))+(4/(x^2)) = (3x+4)/(x^2)
Answer:
5 must be added to both the terms to get the ratio 4:5.
Step-by-step explanation:
(3+x)/(5+x)=4/5
Therefore,
15+5x=20+4x
=5x-4x=20-15
=x=5
I hope it's helpful!
Step-by-step explanation:
the following things are clear : opposite sides are of equal length, the sum of all angles in a square, rectangle or general parallelogram is 360 degrees, and opposite angles are equal.
so,
y² + 7 = 32
y² = 25
y = 5
2y² = k
2×5² = k
50 = k
the opposite angle of 150 is also 150 degrees.
the opposite angle of x is also x.
so, we have as sum of angles
360 = 150 + 150 + x + x = 300 + 2x
60 = 2x
x = 30 degrees
